Amino-acid sequence of the L-4 light chain of chicken skeletal-muscle myosin.
Tryptic and peptic peptides of the L-4 light chain of chicken skeletal muscle myosin were isolated. The amino acid sequences of all the tryptic peptides were determined. The alignment of the tryptic peptides in the protein was deduced from their homology with the primary structure of the A2 (L-4) light chain of rabbit skeletal muscle myosin. The compositions of the peptic peptides confirmed the alignment. Comparing the whole sequence of the L-4 light chain thus established with that of the A2 light chain of rabbit skeletal muscle myosin, 24 amino acid substitutions were recognized.
